and Andre Application May 28, 1930. Serial No. 456,668 5 Claims. (01. re-4n Our invention relates to improvements in building structures, and has for its object to provide a building block or wall member which is simple in construction, easy to produce, and efficient in use.

Further, said invention has ior its object to provide a building block or wall member formed or plastic material, and having incorporated therein means for insulating certain of its wall portions or sides from other thereof.

Further, said invention has for its object to provide a building block or wall member formed oi plastic material having incorporated therein one or more layers of insulating material for preventing the exchange or transfer oi heat from one side or portion thereof to another side or portion thereoi.

Further, said invention has for its object to provide an interlocking or inter-engaging building block or wall member formed as an integral structure of plastic material having incorporated therein one or more layers or sections of insulating material for preventing the exchange or transfer or" heat from one portion or side to another portion or side thereof.

Further, said invention has for its object to provide a building block or wall member formed as an integral structure of plastic material having incorporated therein, upon or adjacent tocertain of its opposite sides or wall portions rela tiv-eiy thin sheets or layers of insulating material serving to prevent the exchange or transfer of heat from 'one of said sides or wall portions to the other thereof, and serving also to maintain the portion of the block intermediate said insulated portionat a substantially uniforrn or neutral temperature.

Other objects will in part be obvious and in part he pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists in the novel features of construction and'in the combination, connection and arrangement of parts, hereinaiter more fully described and then pointed out in the cioinis' the accompanying drawings, showing illustrative embodiments of the invention- Figure 1 is a perspective showing one term of single block constructed according to, em hearing our said invention;

2 is a perspective view illustrating another shoes or block; 4

is a front view, partly broken away and in section showing a portion oi a wall constructed of blocks of the form illustrated at Fig. 2;

Fig. 4 is a front elevation partly broken away and in section illustrating a modification;

Fig. 5 is a longitudinal section on the line 5-5 of Fig. 4.

Fig. 6 is a transverse, vertical section illustrating a further modification, and

Fig. 7 is a central section showing a mold and the manner of forming a block therein.

In said drawings, referring to Figs. 1 and 2, 1o designates a wall member or building block formed as an integral unit of molded plastic material, such as cement, concrete molded to shape and dried, or it may consist of terra cotta or refractory material, and be formed either as a solid or as hollow cellular block. I

The member or block may be made in any desired shape or size, but is herein shown a rectangular body portion 11 formed, for example, oi concrete having openings 12, 12 extending vertically therethrough separated by an integral partition 13. The term vertically" as herein used refers to the contemplated portion oi the block when built into a wall. The opposite major sides are provided at their vertical edges with raised marginal portion or ribs 14, 14 having their inwardly facing edges undercut at 15,: 15 to receive and retain a layer of heat-insulating material 16 such as asbestos, whose center surface is substantially flush with the outer surfaces or the marginal portions i l, 1%. Que outer or vertical side of the block 10 is provided with a layer of plastic material which constitutes the exposed surface or facing 17 oi the block which is designed for exposure when the loclr is in use. In the present instance the outer side of said lacing 1!? is made to simulate a plurality of bricks it, such as are commonly employed in building structures, and suitably scored by lines is to imitate the cement or mortar whereby bricirs are secured in position to form a wall. It will, or" course, he obvious, and it is intended that he iaclns it may be formed of any suitable plastic material, and of any color so as to simulate brick, stone, cement stucco, or other material, and that the same may be plain, smooth surface or be crnented in alto or has relief as desired.

in the modification illustrated at Figs.- 3 and t the wall member or block ic is formed as a nyra mid unit simulating the anearance oi a wall oec=-' joints or seams 19 broken in the usual manner. This form of block nossesses the advantage that alternate hlocizs may be reversed, as shown by broken lines, and thus produce the appearance oi an ordinary brick wall. The unit, except tor its Eli) j i tion composed oi six bricks lil having is constructed substantially like that shown at.

Fig. 1, except that in t instance body portion 11 is preformed and provided in its front face with a plurality of under-cut or dovetail recesses 12*, to receive anchoring members 13*; 13 formed integrally with the facing 17 and extending through the heat-insulating layer 16 in order;

may be more firmly sethat the several parts cured together. Where desired or necessary the inner or rear face of the block may be formed with similar anchoring means for its facing.

In the modification illustrated at Fig. 6, the block 10 has its central or body portion 11 formed of cement or other suitable material, as hereinabove described, and has its outer facing 20 on its outer surface which is composed of a mixture of plastic material and heat-insulating material, such asasbestos integrally molded with the body portion ll. The inner or rear surface of the block in the present construction is formed entirely by an insulating block 16 of asbestos or the like.

In producing a wall member or block according to our invention, we take a mold, have the inner side of its base shaped to produce the exterior surface of the unit, and first pour into the mold a quantity oi. plastic material to constitute the facmaterial is still plastic the length of the block and its shorter edges bevelled as shown. Hereupon the plastic material constituting the body of the block is poured into the mold to within a short distance of the top thereof, and the inner slab or layer ofinsulating It is to be noted that by means or our invention, we are enabled to provide a building block or unit which will reduce to a the exchange or transfer of heat. Thus by reason of the slabs or layers near the inner and outer sides of the block, the interior of a building will be protected and insulated against the transfer of cold from with out, and at the same time the transfer of heat from the interior of the building to the outside material incorporated into of insulation arranged at, or

will be prevented. The central-part of the block between the insulating slabs or layers will therefore at all times possess a uniform or neutral temperature.

Having. thus described our said invention, what we claim and desire to secure. by Letters Patent is.

insulating material, substantially as specified.

2. A wall member formed as an integral unit comprising a block of molded plastic material, a layer of insulating material incorporated into the same along one vertical face thereof, and a facing of plastic material covering said layer of insulating material, substantially'es specified.

3. A wall member composed of material formed as an integral unit of pyramidal form with stepped sides, and insulating material incorporated the same adjacent to certain of its sides, a. portion of said plastic material serving to cover said insulating material, and

stantially as specified.

' 4. A wallmember composed material formed as an integral unit of pyramidal form-with stepped sides, and having vertical openings extending therethrough, and insulating material incorporated into the, same adjacent to certain of its sides, a-portionoisaid plastic material serving to cover said insulating material, and constituting the facing of said wall member, substantially as specified.

5. A wail member comprising a block-of molded material, a' relatively thin layer of insulating the same upon at portions, and finishing facing disposed uponand united with said insulating material, substantially as DONALD A. some. ANDRE M. mrzsnore.
